guages, Hebrew, Greek, and Latin ; but speaks not a Word of the Sclavonian. 3. That he calls thofe of his own Language the Latins, which our Author proves out of his Apology against Ruffin, his Letter to Theophylactus, his Preface upon Joshua and Job, and quotes Richard Simon, Nicolaus Serrarius, and Frenzelius, who were of the fame Opinion with him. Their other Arguments are but trifling: Theodoretus in his 5th Book de curandis Græcorum affectibus, fays, the Bible was tranflated into all the Languages under the Sun, the Scythic and Sauromatic; but if one reads Ovid and St. Jerom himself, he will find the Sauromate were not at all Sclavonians, but the fame with the Geta, a People near Pont-Euxin. whofe chief City was Tomos. Eufebius in his Panegyrick upon Conftantine affirms, the Holy Scriptures were tranflated into all Languages, as well of the Barbarian as of the Greeks, and Anaftafius Sinaira in his Hodegus fays, they were written in feventy-two different Languages and Letters. But befides, that thefe Expressions are very hyperbolical, they don't prove there was a Sclavonian Tranflation, and lefs ftill that St. Jerom was the Author of it. How this Opinion came to prevail, is a Queftion that deferves to be ftrictly examined: our Author makes fome curious Remarks upon it: he fhews, 1. Out of a Fragment of Freherus, Aventin, Eneas Sylvius, Pope John VIIIth's Letters, and many other Hiftorians, that Cyrillus and Methodius introduced the ufe of the Sclavonian Language in divine Service, not compell'd to it by the Outcries of the Common People, or the Threatnings of the Bohemians, as Dubravius falfely relates, but of their own accord, or ra

ther

ther in Imitation of the Greeks, who always made ufe in their Worship of their MotherTongue. 2. That the Pope, upon fome Com plaints made by the Archbishop of Saltzburg of this Innovation, fent threatning Letters to Meihodius, wherein he forbids the use of the. Sclavonian Language in divine Service; but finding Methodius refolved not to give up this Point, and fearing the Sclavonians would follow the Example of thofe of Bulgary, and put themselves under the Protection of the See of Conftantinople, he condefcended at last to authorize the use of the Sclavonian Tongue. 3. That to ward off the Blow, which this new Practice might give to the Pope's Authority and Infallibility, the Monkifh Writers, according to their custom, had recourfe to Fables, and pretended not only, that when the Cafe was debated at Rome, a Voice was heard from Heaven, faying, O praife the Lord all ye Nations; but also, that the Sclavonian Bible was the fame with the Latin, having been translated by the fame Author. Mr. Kohl adds to this, a fuccinct Relation of the Birth, Life, and Actions of Methodius and Cyrillus, as well as fome Obfervations upon feveral other Tranflations of the Bible, the Pfalms, and the Gofpels in theSclavonian Language; and fome very curious Remarks upon the religious Customs of the Muscovites, whereof he has been an Eyewitness.

To fatisfy the Curiofity of our Readers, we shall give a particular Abstract of all this in our next Journal.

Hiftoire de l'Academie Royale des Sciences, Année 1728, avec les Mémoires pour la même Anné.

The History and Memoirs of the Royal Academy of Sciences at Paris, for the Tear 1728. Paris printed in 1730. 4to.

I

N the first Volume of our Journal, Art. IV.

we have given an Account of this History for the Year 1727; and we intend for the future to adorn our Journal with the Discoveries and Improvements made in Natural Philofophy, by the learned Members of the Royal Academy at Paris. This Volume contains many curious Articles, as well in the History as in the Memoirs; we'll give an Account of thofe that seem the most entertaining, and that are suited to every Capacity.

THE firft Article of the Hiftory contains fome Obfervations and Experiments touching the Loadstone. It has been obferved, that an Iron Bar left standing perpendicularly for fome time, acquires a magnetical Virtue: this has also been found true in Tongs and Shovels, that had been left in the Corner of a Chimney during the Summer: but if a Bar be left borifontally, it will not acquire any Virtue. If an Iron Bar be put horisontally near a Compassneadle, the Needle will remain ftill, tho' the Bar be never fo near to it: but if you move the Bar in fuch a manner, that one end remaining unmoved, the other defcribe the fourth part of a

Circle,

Circle, and the Bar become perpendicular, thence the uppermoft end will fuddenly draw to it the north end of the Needle; and if the Bar be moved upwards perpendicularly, the lower end of it will draw the fouth end of the Needle. If you repeat the Experiment, having only changed the Situation of the Bar, in fuch a manner, that the end, which in the firft Experiment was the uppermoft, be now the lowest, the fame thing will happen revertheless; the end now uppermost will still attract the north end of the Needle, and the lower end will at tract the fouth; fo that the fame end of the Bar, which in the first Experiment did attract the north, attracts the fouth in the fecond Experiment: it appears by this, that the Poles of the Bar change Places; and what is more furprifing, they change fo eafily, that you may repeat the Experiment as often as you please. But here it must be obferved, that the Experiment fucceeds only when the Bar has not before-hand acquir'd any magnetical Virtue; and this may be known by putting the Bar horifontally near the Needle; if no Motion is obferved in the Needle, it is a fure proof, that the Bar has not acquir'd any Virtue. In the Experiment we mention'd, the Bar being in a perpendicular Situation, and one end being near the Needle, if you move the Bar upwards, keeping it always in the fame Situation, the upper end will draw the north end of the Needle, till the middle of the Bar be in the fame horisontal Plain with the Needle; then the Needle turns, and the fouth end of it is drawn by the lower end of the Bar, which, (the Bar moving still upwards) is now nearer to the Needle than the upper end. But here, when we fpek of the

mid

middle of the Bar, we fuppofe, that the Bar be uniform and even, fo that its middle Part be alfo its Centrum gravitatis: if this be not, the Needle will turn only when the Centrum gravitatis fhall be in the fame Plain with it. These Phænomena feem very hard to explain. Mr. Du Fay has nevertheless found out an Hypothefis, by which he thinks it poffible to account for them all, but as it is only an Hypothefis, we don't think it neceffary to translate it; and we refer the Reader to what Mr. de Fontenelle fays of it in the Article, of which we have extracted the foregoing Phænomena, and to Mr. Du Fay's Obfervations, which are to be found in Page 355. of the Memoirs.

THE Articles relating to Anatomy follow next: The four firft being only Abstracts of what is found alfo in the Memoirs, we'll put them off, till we come to give an Account of the Memoirs. We find next, We find next, two Obfervations, of which the firft deferves to be taken notice of. In the Year 1692, a Notary of Sale in the Sevennes, received a Kick on the forepart of his right Thigh: A little while after there appear'd on that part a Tumour or Swelling, which however was not painful, but did continually grow bigger, tho' at firft very flowly. Mr. Guisard a Phyfician, advised the Patient to ftop the Courfe of this Evil betimes; but as it did not fmart, it was neglected. When the Tumour or Wen was become of a certain bignefs, it increafed apace; and in the Year 1714, it took up the whole length of the Thigh from the top to the Knee, and was as big as the Forms of two Hats joined together, and was thought to weigh then 30 pound. It was now too late to undertake to cure it. In 1727,
